during an investigation, a scientist numbers three beakers. next, she pours 150 ml of liquid into each
beaker. each liquid is different.
then, the scientist adds 5 grams of white solid baking soda (nahco: ) to each beaker and stirs. she
observes the results.

What volume of 0.500 mol/l hydrochloric acid, hci (aq) is required to react completely with 1.00 g of aluminum hydroxide, ai(oh)3 (s)?

Describe the structure of ammonium lauryl sulfate. refer to the given diagram. your answer should include the type of bonding, the elements contained, and the size and shape of the molecule. write a short paragraph.

In a modern periodic table, there are seven periods. a period is any horizontal row of the periodic table, and the elements in a period have consecutive atomic numbers. a group is any vertical column in the periodic table, and there are 18 such groups. groups 3–12, also known as the “b” group elements, are called transition metals. groups 1–2 and 13–18, also known as the “a” group elements, are sometimes called the main groups. metals are characterized by malleability, ductility, conductivity, and a tendency to lose electrons. main group metals are found in groups 1 and 2. nonmetallic elements fall on the right-hand side of the periodic table, that is, groups 13–18. nonmetals have the tendency to gain electrons and are generally brittle. they can be solids, liquids, or gasses at room temperature. now, label the areas of the modern periodic table using the above information. drag the appropriate labels to their respective targets.
